Darithis the Bleak is NOT spawning

Blizz GM Smoehattes suggested I post here on the tech forum.

Darithis the Bleak isn’t spawning. I’ve been camping it 7-8 hours per day for the last few days (monitor next to me while I work from home).

Not only have I not seen him, NOTHING else spawns in his cave, and I know there used to be items and MOBs in it.

I’ve disabled my add ons, renamed my cache, interface and WTF folders to cacheold, interfaceold and WTFold, waited for server reset and still nothing is spawning in the cave. There is nothing new on any of the internet communities like wowhead or icyveins talking about this.

He is a requirement for the Better to Be Lucky Than Dead achievement, which leads to the Maw Walker title.
